Class NameAnalyzer.FindDeclarationsAndSetters

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractPostOrderCallback

com.google.javascript.jscomp.NameAnalyzer.FindDeclarationsAndSetters

All Implemented Interfaces:

NodeTraversal.Callback

Enclosing class:

NameAnalyzer

private class NameAnalyzer.FindDeclarationsAndSetters
extends NodeTraversal.AbstractPostOrderCallback

Identifies all declarations of global names and setter statements affecting global symbols (assignments to global names). All declarations and setters must be gathered in a single traversal and stored in traversal order so "removeUnreferenced" can perform modifications in traversal order.

Method Detail

visit

public void visit(NodeTraversal t,
                  Node n,
                  Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in postorder (after its children have been visited). A node is visited only if all its parents should be traversed (NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node)).

Implementations can have side effects (e.g. modifying the parse tree).

recordSet

private void recordSet(java.lang.String name,
                       Node node)

Records the assignment of a value to a global name.

Parameters:

name - Fully qualified name

node - The top node representing the name (GETPROP, NAME, STRING [objlit key], or CALL [Object.defineProperties])

recordPrototypeSet

private void recordPrototypeSet(java.lang.String className,
                                java.lang.String prototypeProperty,
                                Node node)

Records the assignment to a prototype property of a global name, if possible.

Parameters:

className - The name of the class.

prototypeProperty - The name of the prototype property.

node - The top node representing the name (GETPROP)

recordWriteOnProperties

private void recordWriteOnProperties(java.lang.String parentName)

Record that the properties of this name have been written to.
